Contact a few real estate agents and request a free market analysis of your home. With three opinions you should have a very good idea of the market value. While you are speaking to the agent's, mention the specific property you are referring to, and ask them about any discrepencies. It's always best to get several expert opinions rather than relying on less reliable sources of information.
